It's the end of the world as we know it. Trixie Collins is a normal teen making her way through high school. One night at a party, a boy comes on to her and won't take no for an answer. As she jerks her arm away, his fingernails cut into her skin. When she finds her dog's mutilated body and realizes she's to blame, she starts to think maybe the zombie apocalypse they've been screaming about on the news isn't a hoax after all. Worse, she begins to think maybe she's one of the infected. Now it's a fight for life as she joins together with her brethren to stop the humans intent on destroying them. Are zombies all bad, or is it just a huge misunderstanding?
